How to Install a Moen Kitchen Faucet? This is 6 Superb Installation Guide!

Blog, How To

We moved a few months ago and the thing I disliked most about this house was the faucet. We’re confused about how to install a Moen Kitchen Faucet, we’re not kidding! They installed the smallest and cheapest faucet they could find. The kitchen faucet didn’t even have a diffuser spout so the water just came out. Not only what I needed but it was beautiful. I’m pretty sure this is the easiest moen kitchen faucet installation ever. maybe you will be interested in reading a Moen Kitchen Faucet Quality Review that will help you.

Instructions for installing the Moen single handle kitchen faucet, like any other faucet, will vary slightly by model. In this example, you will see how to remove an old faucet and install a new Moen Harlon series faucet, but the installation procedure will be similar for almost all Moen kitchen faucet models with one handle and a retractable spout. This particular model includes a pre-installed flexible water supply line with a 3/8 inch compression fitting (screw). If your shut-off valve under the sink is 1/2-inch instead of 3/8-inch, connect the supply line with a 3/8-to-1/2-inch compression adapter.

Equipment / Materials For Install a Moen Kitchen Faucet 

Basin wrench
A basin wrench, sometimes called a sink wrench, is a plumbing tool which is used in confined spaces to turn fasteners that would be difficult or impossible to reach with a plumber wrench or other types of wrenches. For example, the threaded nuts used to secure faucets to sinks are often located in deeply recessed places that can only be accessed with a basin wrench.

Adjustable Wrenches

An adjustable spanner (UK and most other English-speaking countries) or adjustable wrench (US and Canada) is any of various styles of spanner (wrench) with a movable jaw, allowing it to be used with different sizes of fastener head (nut, bolt, etc.) rather than just one fastener size, as with a conventional fixed spanner.

There are many forms of adjustable spanners; many of them are screw-adjusted, whereas others use levers, and some early ones used wedges.


A bucket is typically a watertight, vertical cylinder or truncated cone or square, with an open top and a flat bottom, attached to a semicircular carrying handle called the bail.

A bucket is usually an open-top container. In contrast, a pail can have a top or lid and is a shipping container. In common usage, the two terms are often used interchangeably.

Putty Knives

A putty knife is a specialized tool used when glazing single glazed windows, to work putty around the edges of each pane of glass. An experienced glazer will apply the putty by hand, and then smooth it with the knife. Modern insulated glazing may use other ways of securing the glass to the window frame.

A spackle knife (called a scraper in British English, also known as a spatula in American English) is also commonly called a “putty knife”, and is used for scraping surfaces or spreading material such as plaster in various construction trades. Widths from 11⁄4″ to 5″ or 6″ are commonly available. Wider-bladed knives up to about 12″ are used for sheet rocking. Larger blades are made, but generally lack the stability of the smaller blades and do not make a perfectly flat surface.


  • New Moen single-handle faucet
  • 3/8- to 1/2-inch compression adapters (as needed)

Instructions For Install a Moen Kitchen Faucet 

Disconnect the Water Supply

Shut off the water to the old faucet by closing the fixture shutoff valves on the hot and cold water supply pipes under the sink. Turn the shutoff valve handles clockwise until they stop. Check to make sure the water is off by turning on the faucet.

Disconnect the faucet’s flexible supply tubes from the shutoff valves, using channel-lock pliers. Hold the valve body in place with one pair of pliers, and loosen the compression nut on the supply tube with the other pliers.

Remove the Old Faucet

Remove the old faucet by loosening the mounting nut (or nuts) that secure the faucet on the underside of the sink. It helps to have a basin wrench to reach up into this tight space, but channel-lock pliers will also work. Once the nut is loosened, unthread it all the way by hand, then pull the faucet up and away from the top of the sink. If the faucet has an attached sprayer, disconnect the nut holding the sprayer hose to the faucet, as well as the mounting nut holding the sprayer tailpiece to the sink.

With faucet and sprayer removed, clean the top deck of the sink to remove any stains left at the base of the faucet. Chances are the footprint of the new faucet will be slightly different, and the better you clean the top of the sink, the better it will look.

Install the New Faucet Body

Install the deck gasket onto the trendy faucet thru turning into it over the flexible supply strains and sliding it up into the faucet body. Feed the supply tubes through the hole withinside the sink deck, and center the faucet body over the hole. Position the faucet in that you want it and ensure it fits well in advance than going below the sink to solid it.

Secure the Faucet

Place the square help plate into role on the bottom of the sink, becoming it over the deliver tubes and the threaded tailpiece of the tap frame and up towards the lowest aspect of the sink. Place the spherical plate beneathneath the square plate, then thread the brass mounting nut onto the tap tailpiece. This tailpiece is likewise the housing for the sprayer hose.  Use the set up device supplied with the tap to tighten the mounting nut maximum of the way. Check the placement of the tap above the sink, then end tightening the mounting nut till the tap is tight sufficient that it may not move.

Install the Sprayer Hose

Screw the spray hose housing nut onto the quit of the tap tailpiece, then connect the spray hose to the tap spray wand via way of means of screwing it on. Feed the opposite quit of the spray hose into the tap spout till the quit comes out beneathneath the sink. Remove the white cap from the quit of the spray hose. Connect the spray hose to the frame of the tap via way of means of pushing the hose into function and the usage of the white clip to maintain it in place.

Attach the load onto the spray hose, positioning it close to the white tape at the hose. The weight need to pass up and down freely with the spray hose; take a look at it via way of means of transferring the spray wand inside and out of the tap spout. The hose need to pass without difficulty with out hitting something beneathneath the sink.

Connect the Water Supply Tubes

Connect the recent and bloodless deliver tubes of the tap to the shutoff valves on the recent and bloodless water deliver pipes, the usage of compression fittings. Thread the compression nut for every line onto the corresponding shutoff valve and tighten the nut with pairs of pliers one to keep the valve frame and one to tighten the nut.

Make sure the bendy tubes might not intrude with the spray hose and aren’t kinked. Turn the water lower back on with the aid of using beginning the shutoff valves all of the way (turning counterclockwise). Check the tap for correct operation and verify there aren’t anyt any leaks withinside the bendy tubes or the spray hose.


Installing a Moen Kitchen Faucet can be a fairly simple process, and new faucets should come with manufacturer specific instructions. Keep in mind, most pitfalls will come with the angle stops and flex lines, so be careful of their condition prior to starting and know where your main water shut off is located in case of an emergency.
